Despite what people think, a cappuccino can NOT be iced. In America, there are two types of cappuccinos, wet and dry. Wet caps are about 1 part espresso, 1 part steamed milk, 1 part foam. A dry is 1 part espresso, 2 parts foam.
In Italy, the difference between a Cappuccino and a Cafe Latte is not the amount of foam on top, but the consistency of the milk. Cafe Lattes are more dense, closer to the consistency of milk alone. Cappuccinos has air steamed throughout the entire drink, and therefore is more of a "fluffy" drink.
